The notion of complex analytic space is the notion of analytic space in complex geometry; the generalization of the notion of complex manifold to spaces with singularities.


A complex analytic test space is a common vanishing locus of a set of holomorphic functions n\mathbb{C}^n \to \mathbb{C}. This is naturally a locally ringed space over the complex numbers \mathbb{C}. A complex analytic space is a locally ringed space over \mathbb{C} that is locally isomorphic to such a complex analytic test space.


Local contractibility

A smooth complex analytic space is locally isomorphic to a polydisc and hence locally contractible. See also (Berkovich, p.2).
